Abstract: Domestic food cooking apparatus including a container for holding a food product to be prepared and defining a heating surface and electrical resistance heating apparatus fixedly associated with the container in electrically insulated touching relationship with the heating surface.

Abstract: A human hair depilatory device including a hand held portable housing, a first element arranged to be driven in rotational motion relative to skin bearing hair to be removed, the first element comprising a plurality of hair engaging locations at which adjacent hair engaging surfaces of the first element are spread apart when the hair engaging locations are disposed by rotation at a convex side and at which the adjacent hair engaging surfaces of the first element are moved relatively towards each other in hair engaging arrangement when the hair engaging locations are disposed by rotation at a concave side, the rotational motion of the first element producing motion of the hair engaging locations from the convex side to the concave side for engagement and removal of hair from the skin and a second element disposed interiorly of said first element and arranged to be driven in rotational motion and to define a hair support for hair engaged between adjacent hair engaging surfaces.

Abstract: An electrically powered depilatory device including a hand held portable housing, a hair engagement and removal assembly including elongate elements in mutually twisted engagement and a motor for driving the elongate elements in motion, whereby hair is engaged between the elongate elements and thus removed.

Abstract: A depilatory device comprising a hand-held portable housing, motor apparatus disposed in the housing; first and second helical springs arranged to be driven by the motor apparatus in rotational sliding motion relative to skin bearing hair to be removed, the first and second helical springs each including an arcuate hair engaging portion arranged to define a convex side at which the windings are spread apart and a concave side corresponding thereto at which the windings are pressed together, the rotational motion of the helical spring producing continuous motion of the windings from a spread-apart orientation at the convex side to a pressed together orientation at the concave side for engagement and plucking of hair from the skin.

Abstract: An electrically powered depilatory device including a hand held portable housing, motor apparatus disposed in the housing, and a helical spring comprising a plurality of adjacent windings arranged to be driven by the motor apparatus in rotational sliding motion relative to skin bearing hair to be removed, the helical spring including an arcuate hair engaging portion arranged to define a convex side whereat the windings are spread apart, and a concave side corresponding thereto whereat the windings are pressed together, the rotational motion of the helical spring producing continuous motion of the windings from a spread apart orientation at the convex side to a pressed together orientation at the concave side and for engagement and plucking of hair from the skin, whereby the surface velocities of the windings relative to the hair greatly exceeds the surface velocity of the housing relative thereto.

Abstract: A skin-hair plucking device including a compact coiled member within a housing with a substantially smooth external surface exposed for the slidable engagement with the skin and motor driven means for alternately extending and reclosing the windings.
